Specification of Letters Patent.

Application filed August 3, 1906 Serial No. 329,063.

To u/Z/ Irr/i-om it 'ntrty concern:

Be it known that I, DEAN B. Enwanns, a subject of the King of England,residing at auehopenn the Province of Saskatchewan, Dominion of Canada,have invented certain new and useful Improvements in Drills; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and. use the same.

This invention relates to farm implements and more particularly todrills and has for its object to provide a drill in which the manuallyoperable mechanism for moving the shoes into and out of the ground willbe eliminated, a mechanism operable by the team drawing the drill beingsubstituted therefor. Other objects and advantages will be apparent fromthe following description.

In the drawings forming a portion of this specification and in whichlike numerals of reference indicate similar parts in the several views,Figure 1 is a top plan view of the present invention. Fig. 2 is an endelevation. Fig. 3 is a detail view showing the dog and the operating rodconnected therewith. Fig. 4 is a view similar to Fig. 1, showing theparts in the position in which they occupy when. the shoes are raisedinto inoperative position. Fig. 5 is an elevational view of a modifiedform of the invention. Fig. 6 is a front view of the structure shown in5. Fig. 7 is a detail sectional view on line zra: of Fig. 6, showing thearrangement of the latch rib.

Referring now to the drawings, there is shown a planter including aframe 5 to which there are connected shoes 10 for movement into and outof the ground, these shoes being carried by spouts 11 which are pivotedupon a shaft 12. Levers 6 extend upwardly from the shaft for movementtherewith, and these levers are connected at their upper ends by meansof a rod 7.

Boxing's S are mounted upon the frame, and journaled therein, there is alongitudinally extending shaft 9 having spaced cranks 13 therein and acrank 14 located at its cen ter and between the first named cranks.Pulleys 15 are ournaled vertically upon the frame and have engagedtherewith chains 16 connected at their forward ends with the cranks 1Sand at their rearward ends with the rod 7. An upwardly extendingsupplemental frame 17 is secured to the frame 5 and has secured theretohelical springs 18, which are also secured to the rod 7, these springsbeing arranged to hold the rod yieldahly against forward movement andwith the shoes 10 in operative position, though it will be understoodthat the springs will allow the shoes to move upwardly should theystrike any solid obstruction.

Connected with .the frame 5, there is a draft beam 19 which extendslongitudinally of the frame from the front to the rear thereof and whichalso projects beyond the front and slidably mounted upon this beam,there is a block 20 having a double tree 21 pivoted thereupon at itsforward end. The block is provided with a pair of longitudinally spacedsockets and 223 in one of its side edges, and pivoted. upon. the beam .19 there is a dog 2 tadapted for engagement in the socketsinterchangeably to hold the block against movement, it being understoodthat the block is movable slidably to bring its sockets successivelyinto position to receive the dog.

Chains 25 are ermnectod with the central crank 1.4 of the shaft 9 andwith the block 20 and the arrangement is such that when the block ismoved forwardly, the shaft will be moved to move the rod 7 forwardly anddowmvardly through the medium of the chains 16, thus brii'iging theshoes 10 into the ground. A hand lever 26 is -pivoted upon the beam 19within reach of the operator of the implement and is connected with thedog 24 by means of a rod 37 for operation of the dog, and it will thusbe seen that when it is desired to raise the shoes, the dog being in theforward socket it is but necessary to move the lever to bring the dogout of the socket when the block 20 will be moved backward by thesprings to raise the shoes as just described, and the latter may be heldin raised position by opera-ting the handle 26 to bring the dog into therearward socket 23. When it is desired to lower the shoes, it is butnecessary to move the dog out of operative position when the forwardshaft of the team will move the block 20 forwardly and move the shoesinto operative position when the dog 241-. maybe moved into the socket233 In l igs. 5-7 there is shown a modified form of the invention, inwhich a red A has angular end portions B pivoted to the frame 5 and thisred is connected with the rod 7 for simultaneous movement therewith. Acon tral draft beam C is provided, and has pulleys D journalod up on itsopposite side faces. Depending hangers E are pivoted at their upper endsto the side faces of the draft beam and have a transverse bar F engagedin their lower ends, with which there is connected a whifi le tree G.Chains H are engaged beneath the pulleys I) and are secured at theirrearward ends to the rod A and at their forward ends are connected withthe bar F, and engaged transversely in the hangers E above the bar F,there are a pair of upper and lower spaced rods I and K respectively.

An arm L extends downwardly and forwardly from the frame, and projectsbetween the rods I and K, cross-pieces M being engaged through the armto limit the movement of the hangers, as will be readily under:

stood, through engagement of these crosspieces by the rodsI and K, andpivoted to the arm L for vertical movement there is a latch rod N havingdepending projections O and O inspaced relation, these projectionshaving upwardly convergent mutually adjacent faces and straight oppositefaces 0 and O respectively. An angle lever P is pivoted upon the draftbeam C and'has a depending link Q connected with one of its arms andwith the latch rod N, while the rearwardly extending rod R connects theother arm of the angle lever with a hand lever S corresponding to thelever 26.

As will be seen from the drawings, the hangers E are movable to engagethe rod I forwardly of the forward projection 0 or rearwardly of therearward projection 0 and the hand lever S may be operated to raise therod N and bring both of these projections out of position for engagementby the rod I.

It will thus be seen that forward movement of the lower ends of thehangers re sultant from the pull of the team, will bring the red Iforwardly of the projection O, the latter preventing rearward movementof the hangers, and the shoes will thus be forced into the ground untilthe team is pulled up and the latch rod raised, when the springs 18 willtend to move the shoes out of the ground l and their action will engagethe rod I behind l the rearward projection 0 The shoes will j thus beheld out of the ground until the latch f rod is again raised. 1' IVhatis claimed is: l 1. In a planter, the combination with a I frame, ofshoes connected therewith for movement into and out of operativeposition, means for holding the shoes yieldably in operative position, awhiffle tree slidably connected with the frame, connections between theshoes and whil'lie tree for movement of the shoes in o inoperativeposition when the whiffle tree is slid in one direction, and means forholding the whiflie tree at times against movement and with the shoes inoperative position and at times with the shoes in inoperative position.

In a machine of the class described, the combination with a frame, ofground-treating devices connected with the frame for movement into andout of operative position, s zirings arranged to hold said devicesyieldably in operative position, a shaft journaled upon the frame,connections between the shaft and ground-treating devices for movementof the latter against the action of the l l f r l l r 1 l springs whenthe shaft is moved, a movable l j member connected with the frame,connections between the member and shaft for movement of the shaft tomove the groundtreating devices when the member is moved, means forholding the member at times with j the ground-treating devices inoperative pol sition and at times with them in inoperative l position, awhiffletree connected with the l member, and means for moving thememberholding means into and out of operative posif tion.

In testimony whereof, IafliX j in presence of two witnesses.
